Experimental Design
What is the aspect of the experiment that must remain the same?
Constant/Control
This is the amount of protons in an atom.
Atomic Number
What are the components of the phospholipid bilayer and what are their properties?
Hydrophobic tails, hydrophilic heads
What is the monomer of a carbohydrate?
Monosaccharide
This organelle contains the genetic information in eukaryotic cells.
The Nucleus
What is the aspect of the experiment that is being changed?
Independent Variable
How many neutrons are in Carbon-14?
8
Is facilitated diffusion active or passive transport?
Passive
Which type of fat contains "kinks" and is liquid at room temperature?
Unsaturated Fats
This organelle is in both prokaryotes and eukaryotes to make proteins.
Ribosomes
What is the outcome of the experiment, based on the experimenter's changes?
Dependent Variable
This property of water causes individual molecules of water to stick to surfaces other than water.
Adhesion
What does it mean for something to be amphipathic?
It contains both hydrophobic and hydrophilic regions.
What is characteristic of secondary structure of protein folding?
Alpha helices and Beta Pleated Sheets
This organelle uses energy stored in carbohydrates to produce ATP for use by the cell, through a process called cellular respiration.
Mitochondria
I am completing an experiment to test how high plants will grow based on how much I water them. What is the independent variable?
The amount of water in each plant
Is CH3 polar or nonpolar?
nonpolar
If the solution a cell is present in is hypotonic, what may happen to the cell?
It will swell and potentially lyse, or burst.
What are the 5 nitrogenous bases found in a nucleotide? Which is only present in DNA, and which is only present in RNA?
Adenine, Thymine (DNA only), Cytosine, Guanine, Uracil (RNA only)
Which face of the Golgi apparatus faces the nucleus?
Cis
I hypothesize that the amount of caffeine I drink causes me to be more hyper. How would you design this experiment? (IV, DV, constants, etc.)
Independent: Amount of Caffeine
Dependent: How hyper I am
Constants: Type of caffeinated drink, time of day caffeine is consumed, amount of exercise, diet, etc.
Would a lipid dissolve in water?
No, lipids are nonpolar
What are the three types of endocytosis? Describe what each means.
Phagocytosis - cell takes in large things (cell eating)
Pinocytosis - cell takes in small solutes (cell drinking)
Receptor-Mediated Endocytosis - requires receptors to be bound in order for them to be taking into the cell
Name 3 steroid hormones? How would you identify these?
Testosterone, Cortisol, Estrogen, Progesterone
Identify the 4 ring structure
This organelle contains enzymes to break down and excrete or recycle cell parts that are harmful or unnecessary.
Lysosomes
